I've just recently tested (for reliability) and now carry Speer Gold Dot 180gr that I bought from ATG. It's the Law Enforcement version. I just bought a box(50) from Sportsman's Warehouse for $15 less than ATG. It doesn't say law enforcement. It also is 180gr GDHP.
Is this the same ammo?
BTW... They also had Blazer loaded with GDHP bullets. Never seen that before. They were only a couple of dollars less so I went for the real thing.
